Junior Subordinated Debentures |
Junior Subordinated Debentures | Note 8 – Junior Subordinated Debentures ​ The Company issued $25.0 million of cumulative trust preferred securities through a private placement completed by an unconsolidated subsidiary, Old Second Capital Trust II, in April 2007. These trust preferred securities mature in 30 years, but subject to regulatory approval, can be called in whole or in part on a quarterly basis commencing June 15, 2017. The quarterly cash distributions on the securities were fixed at 6.77% through June 15, 2017, and now have a floating rate of 150 basis points over three-month SOFR. Upon conversion to a floating rate, a cash flow hedge was initiated which resulted in the total interest rate paid on the debt of 4.48% for the quarter ended June 30, 2025, and 4.49% for the quarter ended June 30, 2024. The Company issued a $25.8 million subordinated debenture to Old Second Capital Trust II in return for the aggregate net proceeds of this trust preferred offering. The interest rate and payment frequency on the debenture are equivalent to the cash distribution basis on the trust preferred securities. ​ ​ ​ The junior subordinated debentures issued by the Company are disclosed on the Consolidated Balance Sheets, and the related interest expense for each issuance is included in the Consolidated Statements of Income. As of June 30, 2025, and December 31, 2024, the remaining unamortized debt issuance costs related to the junior subordinated debentures were less than $1,000 and are included as a reduction to the balance of the junior subordinated debentures on the Consolidated Balance Sheets. The remaining deferred issuance costs on the junior subordinated debentures related to the issuance of Old Second Capital Trust II will be amortized to interest expense over the remainder of the 30-year term of the notes and are included in the Consolidated Statements of Income.
